Abstract
Flexible polyurethane foams are made using certain hydrolysable silane compounds in the foam formulation. The hydrolysable silane compounds contain at least one isocyanate-reactive group and at least one hydrolysable silane group. The presence of the hydrolysable silane compound in the foam formulation leads to improved tensile, tear and elongation properties without an adverse effect on other important foam properties such as resiliency and hysteresis loss.
